I use one of those, excellent quality. Don't listen to people that have not tried it, I have tested the Vivitar one against my
SP adaptall one on my 90 Macro and it is as good but much more flexible.
What I am planing to do is modify it to do AF by adding a drive shaft from an old lens.
Sure you will have fun with it.
That's what I needed to hear.
As far as auto focus goes, that doesn't matter to me. I never use auto focus in macro.
What matters is being able to adjust aperture.
If I can find a way to get the glass out of this thing it will make a damn fine adjustable extension tube.
The thing is brand new and I bought it with ebay bucks, so it was essentially free.
They also seen to be really rare. ANYTHING having to do with super macro and the Pentax 100mm WR is really RARE.
It's such a darn fine lens though. I just hate to go to anything else.
